KAMA, a large river of European Russia, the principal affluent of the Volga. It rises in the government of Viatka, N.E. of Glazov, flows first N. and then N.E. into the go-
vernment of Perm, where it takes a S.W. direction; it afterwards separates the government of Viatka from those of Perm and Orenburg, and, entering Kasan, joins the Volga, after a course of more than 100 miles. One of its affluents is connected with an affluent of the Dwina by a canal 12 miles in length, thus establishing water communication between the White Sea and the Caspian.
